+ | For a given boundary, this solver computes the nodal stress equivalent to a given nodal force. Force here means the result of a variable, named stress, which is of the same units than the force but per unit-area in 3D or unit-length in 2D. This can be used also to infer the flux from the value of a debit or to infer a tangential stress from the value of a tangential force. | ||
